EXPLAINER: States still in play and what makes them that way

The solidly Republican state of Alaska has also not been called because it is only 50% counted and will not release absentee numbers until Nov. 10. It is not expected to impact the outcome.

The Associated Press reviews the states that will determine the presidency:

___

GEORGIA: Outstanding ballots left to be counted and a razor-thin margin

THE BACKGROUND: A razor-thin margin and ongoing vote count are what’s making the Georgia contest between President Donald Trump and Joe Biden too early to call.

Votes are still being counted across the state, though many from counties where Biden was in the lead.

Biden inched past the incumbent in the tally as of 1 p.m. EST Friday, leading by fewer than 1,600 votes of nearly 5 million ballots cast — a lead of about 0.03 percentage points. Under Georgia state law, a candidate can request a recount if the margin is within 0.5 percentage points.

Electoral research conducted by the AP found there have been at least 31 statewide recounts since 2000. Three of those changed the outcome of the election. The initial margins in those races were 137 votes, 215 votes and 261 votes.

Among all 31 recounts, the largest shift in results was 0.1%, in the 2006 race for Vermont’s Auditor of Accounts. This was a low turnout election in which the initial results had one candidate winning by 137 votes. The candidate eventually lost by 102 votes, for a swing of 239 votes.

The average shift in the margin between the top two candidates was 0.019 percentage points.

NEVADA: Race too early to call; vote count will continue for several more days.

THE BACKGROUND: Democrat Joe Biden leads by 1.5 percentage points in Nevada over President Donald Trump, with more than 1.2 million ballots counted.

Overall, officials have tallied a little more than three-quarters of the state’s expected vote. Under state law, ballots postmarked by Election Day will still be counted if they arrive by Tuesday, Nov. 10. Clark County said Thursday it did not expect to complete counting the bulk of its mail votes until this weekend.

Among the ballots still left to be processed in Nevada this year are provisional ballots, including 60,000 in Clark County, where most of the state’s voters live. Those ballots were mostly cast by voters who registered on Election Day and will be counted after officials verify their eligibility to be included.

In a tight race, that could delay the AP declaring a winner. For example, in the 2004 race between George W. Bush and John Kerry, the AP did not call the winner of the election in Ohio until it was able to confirm that Bush’s lead exceeded the number of provisional ballots left to be counted.

Nevada, once a swing state, has trended toward Democrats in the past decade. Trump narrowly lost Nevada in 2016. Bush was the last Republican to win there, in 2004.

Biden’s lead in Nevada stood at 20,352 votes at 1 p.m. EST Friday.

___

NORTH CAROLINA: Race too early to call. Ballots left to count.

THE BACKGROUND: Trump prematurely claimed early Wednesday that he won the state.

“We’ve clearly won North Carolina, where we’re up 1.7%, 77,000 votes with only approximately 5% left. They can’t catch us,” he said during an appearance at the White House. Trump also said he planned to contest the U.S. presidential election before the Supreme Court. It was unclear, exactly, what legal action he might pursue.

Though Trump is correct that he held a nearly 77,000-vote lead, which he maintained Thursday morning, the race is too early to call with up to 116,000 mail ballots left to count, as well as about 41,000 provisional ballots statewide.

As long as those ballots are postmarked by Nov. 3, state election officials have until Nov. 12 to count them. And when it comes to mail ballots, Biden was outperforming Trump. That means the ballots yet to be counted could give Biden a lead.

___

PENNSYLVANIA: Tens of thousands of ballots left to be counted.

THE BACKGROUND: A close margin and a large number of outstanding votes are what’s making the Pennsylvania contest between President Donald Trump and Joe Biden too early to call.

The Democrat opened a lead of about 12,500 votes Friday over Trump, of more than 6.5 million votes cast — a lead of less than 0.19%. State law dictates that a recount must be held if the margin between the two candidates is less than 0.5%.

Elections officials are not allowed to process mail-in ballots until Election Day under state law.

Mail ballots from across the state overwhelmingly broke in Biden’s direction.

There’s also a possibility the race won’t be decided for days. If there is less than a half percentage point difference between Biden’s and Trump’s vote totals, state law dictates that a recount must be held.

Democrats had long considered Pennsylvania a part of their “blue wall” — a trifecta that also includes Wisconsin and Michigan — that for years had served as a bulwark in presidential elections. In 2016, Trump won each by less than a percentage point.

Biden, who was born in Scranton, claims favorite-son status in the state and has long played up the idea that he was Pennsylvania’s “third senator” during his decades representing neighboring Delaware. He’s also campaigned extensively in the state from his home in Delaware.
